Blending Primes and Startups for the Golden Dome
The U.S. Space Force is bypassing traditional procurement to fast-track a $3.2 billion interceptor network. But with an aggressive 2028 deadline, can a mix of legacy aerospace giants and new-space startups deliver?
The U.S. Space Force has kicked off the hardware development phase for its ‘Golden Dome’ missile defence architecture, awarding up to $3.2 billion in contracts for a new constellation of space-based interceptors (SBIs).
Space Systems Command (SSC) announced on April 24 that it has issued 20 Other Transaction Authority (OTA) agreements to 12 different companies. The contracts are designed to rapidly prototype and develop a proliferated Low Earth Orbit (pLEO) interceptor network, with the U.S. military setting an aggressive target to demonstrate an initial integrated capability by 2028.
The SBI program is positioned as a direct response to January 2025’s Executive Order 14186, which mandated the deployment of a next-generation missile shield. According to the SSC, the new pLEO constellation will be capable of boost, midcourse, and glide phase engagements, specifically designed to counter the increasing speed and maneuverability of modern ballistic, hypersonic, and cruise missiles.
“Adversary capabilities are advancing rapidly, and our acquisition strategies must move even faster to counter the growing speed and maneuverability of modern missile threats,” U.S. Space Force Col. Bryon McClain, Program Executive Officer for Space Combat Power, said in a statement. “With the commitment and collaboration of these industry partners, the Space Force will demonstrate an initial capability in 2028.”
To meet that tight deadline, the Space Force is utilizing OTA agreements, a contracting mechanism that allows the military to bypass slower, traditional procurement processes and attract commercial tech companies.
The list of awardees reflects this shift in strategy, blending legacy aerospace primes—such as Lockheed Martin, Raytheon, Northrop Grumman, and General Dynamics—with newer, non-traditional space and defence technology startups, including Anduril, True Anomaly, and Turion Space. GITAI USA, Booz Allen Hamilton, Quindar, and Sci-Tec round out the list of recipients.
Due to operational security requirements, the SSC stated that no further technical information regarding the SBI program will be released at this time.
However, for the broader North American space sector, the accelerated 2028 timeline underscores a rapidly expanding defence market. The deployment of a multi-billion-dollar interceptor constellation will require massive parallel investments in the global satellite tracking, sensor, and optical communications layers required to actually guide those interceptors to their targets.
For the broader North American space industry, this fast-tracked 2028 goal is another signal that a potential boom in space defence spending could be starting. Caution remains, as previous administrations have also signalled pending large investments in hypersonic technologies, only to pull back a few years later.
Still, building a multi-billion-dollar system to intercept missiles will require large parallel investments in the global satellite tracking, sensor, and optical communications layers.
